Qᴜᴀʟᴛʀᴀɴ (quantum algorithms translator) is a set of abstractions for representing quantum programs and a library of quantum algorithms expressed in that language to support quantum algorithms research.
Note: Qualtran is an experimental preview release. We provide no backwards compatibility guarantees. Some algorithms or library functionality may be incomplete or contain inaccuracies. Open issues or contact the authors with bug reports or feedback.

Qualtran is being actively developed. We recommend installing from source:
For a local editable copy:
git clone https://github.com/quantumlib/Qualtran.git
cd Qualtran/
pip install -e .
You can also install the latest tagged release using pip:
pip install qualtran
You can also install the latest state of the main branch:
pip install git+https://github.com/quantumlib/Qualtran
Qualtran provides a GUI for estimating the physical resources (qubits, magic states, runtime, ..etc) needed to run a quantum algorithm. The GUI can be run locally by running:
cd $QUALTRAN_HOME
python -m qualtran.surface_code.ui
